View Full Version : Advice on metering please.

Can anyone advise on how I could have avoided blowing the highlights in the shot below please. Taken with an Olympus E510, Sigma 10-20, F11, 10seconds, iso 100.

The lens had a cpl and a ND grad. I used evaluative metering and this shot is a merge, in PS, of 4 differently exposed shots from one raw file. Would I be right in thinking that if I had used a different metering setting that I could have saved a bit more of the highlights?

Thanks

Beautiful scene, Greg (even better when the horizon is levelled :)).

In one way, I might ask - do you need to recover the highlights? It looks very good as it is.

But if there is detail in there to be recovered, then you would need to expose for the highlight and I would recommend bracketing and then if necessary overlay one or more differently exposed versions and mask in the highlights. HDR is anther option, or you could try shadows and highlights if you are using Photoshop.

What Ian said. I wouldn't have bothered with the ND grad. I'd have bracketed several exposures and then blended one or more differently exposed versions or done an HDR.

Hi Greg, in situations like these I find spot metering the lightest patch of sky near the sun (but not the sun itself) gives a good exposure if shooting raw and you can bracket around it for safety.

Saying that, in this case only one raw exposure was taken and processed in Lightroom 3.3.

Also taken on the very same E-510 you now own.;)

nope, or not necessarily - it's not really a metering issue, and after all that processing we aren't really looking at the output of the metering either.

on a shot like this you can use any metering you want - then adjust the next/final eposure based on the initial 'trial' and histogram.

alternatively flick into exposure bracketting and fire of 5 raw files and deal with it all later because you clearly need more DR than the 510 can give you from 1 file.

having said all that it's a super shot as presented

Hi Greg, sometimes I think we worry too much about "blown" highlights in pictures like this. The truth is, in reality the highlights probably appeared blown to the naked eye anyway! But, as is so often the case, we always want to embellish reality just a bit, don't we? ;)

You've already had some good suggestions for bracketed shots for blending or HDR, but you could still do it the old fashioned craftsman's way with filters. I suspect you used a 2 stop ND grad with the transition aligned with the horizon. I would have stacked a 3 stop soft on top of this, but cutting across the frame at an angle, tracing the line of the edges of the blown areas both in the sky and the water. Some filter systems allow two holders to be stacked and independantly offset, otherwise attach the second filter outside the holder with blutack or hold it in place very carefully.

It's your choice whether to use filters at the time of capture or to post process multiple files, there isn't a right or wrong way. Incidentally, there's a distinctive light-toned patch at the top left of the water which I can't make out. Was it a reflection from a bright patch of sky just out of frame or is it a reflection on lens or filter causing a loss ofcontrast?

Super shot, BTW! :)

In my film shooting days I'd have done something similar using 2 ND grads. I don't think I've used my ND grads in the past three years despite still having them in my camera bag.

Yes, at least now there are a number of alternatives. I do still like to dabble in the dark arts of yesteryear from time to time and despite the E-3's sophisticated metering still use a Pentax digital spot meter on occasions. :D In some ways it was much easier in those days because it was much harder to get great results with transparency film, if you get my drift. :)

Thanks for the reply Ian:)

Yep I love the scene in this shot but when I came to look at it, after processing it, the areas of white just bugged me. On reflection though, you may have a point that there is very little detail there to be recovered. Bracketting is of course an option and one I overlooked at the time:o

HDR is outwith my range of options for the moment but definitely an area I would like to explore further when I eventually purchase Photomatix:)

Thanks Ian*chr

Thanks for the reply David:)

yep, bracketting the shot would have been a clever idea at the time:o It is something I do from time to time but unfortunately ......lesson learned.

I take it you would blend in PS manually? I had a go at manual blending, using elements 8, from the 4 files created from the raw but it was a disaster:(

I have much to learn:)

Thanks David

Thanks for the reply Paul:)

You may find this surprising but here goes:cool: When I was thinking about this, the very shot you posted above, with the bench, came into my head*yes and also your dandelion shot, which I hope you remember:)

Your suggestion of spot metering an area of bright sky also came to me afterwards but I think I read that on the four thirds forum:)

Bracketting the shot seems to have been the correct way to have dealt with this, after correcting the exposure, but then some skill in elements would be required to manually merge the exposures rather than using the photomerge exposure option, which I used. To be honest after struggling through the mud to get to the low water mark, I was knackered:eek: It was getting a bit scary and definitely not a place to take the kids. Just getting a shot was worth it, hopefully.

My impressions of my E510? It is a very capable camera. It will never let me down. It is capable of producing the goods even when the operator malfunctions and like a good guitar it has absorbed its history *chr

Once again though I have a lot to learn and appreciate all the comments and advice from everyone*chr Although if you were of a mind to lead me further in the right direction I would be avery happy fella*yes

Cheers Paul and thanks for a great piece of kit*yes

Thanks for a great reply John:)

your advice regarding angling the grad filter rings a very loud bell*yes You have previously advied me to completely reverse the grad when taking dandelion shots with a very low sun*chr Did I remember that when I took this shot:o

At the moment I am only using my ebay nd grad but hopefully will get a hold of a set of hitech grads very soon. That means in the next year or so;)

You also mentioned the weird area on the left of the shot. The shot below will explain what was happening but I should have cropped it out and straightened the horizon:o

BTW the version you've just posted has close to perfect exposure and needs no adjustment other than a moderate increase in contrast. :)
